x86/cpu/amd: Enable Zenbleed fix for AMD Custom APU 0405
stable inclusion from stable-v5.10.191 commit eda9f8ffca46570acda76ad1da8cb8b8f5ccc5a3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I7NLYY CVE: CVE-2023-20593 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=eda9f8ffca46570acda76ad1da8cb8b8f5ccc5a3 -------------------------------- commit 6dbef74aeb090d6bee7d64ef3fa82ae6fa53f271 upstream. Commit 522b1d69219d ("x86/cpu/amd: Add a Zenbleed fix") provided a fix for the Zen2 VZEROUPPER data corruption bug affecting a range of CPU models, but the AMD Custom APU 0405 found on SteamDeck was not listed, although it is clearly affected by the vulnerability. Add this CPU variant to the Zenbleed erratum list, in order to unconditionally enable the fallback fix until a proper microcode update is available.
